Reaming of oil feed passages on the irons to the stationary gear bearings for increased oil flow; done by Chips Motorsports!
-8 with o-ring groove for a leak proof setup, not pipe threaded like other builders out there.

Because I'm also running a Mazdaspeed dry-sump system Chip will be doing some trick stuff that I'll post later, so stay tuned for some rotary related porn that you've never seen done to a rotary before!

Why didn't you just weld a -8 AN bung on? Could have done away with threaded fittings all together.

Welds are ugly. IMO, this looks much cleaner even over TIG.

Yes sir. Lets see where I left off, hmm...

Brand new 3 x S5 rotor housings and 3 x S4 Low Comp Rotors. The rotors will be lightened next, so stay tuned for pics of that.




Mock Up:







Machined the spark plug dimples off.

and when the weld breaks or the fitting breaks/strips you will know why it's easier to use a softer material for a threaded fitting.



ALL of those coolant walls failed? what did they store the engine with? muriatic acid?
